In to XTech 2008

Our submitted Talk Brief / Abstract has been accepted for XTech 2008. It's not clear who and when we'll be there, but I suspect we'll be there somehow.

Meanwhile the idea that although Quakr is the best idea on the world ever, it might not make us all rich is becoming clearer. After talking to XTech 2007, then being headhunted to talk at Where 2.0, then a couple of possible investors, then getting to the last 30 of 268 companies which applied to Seedcamp, then a couple of other nice people... it seems we're a bit ahead of everything and everyone. We're right of course that the new world will be a user generated environment and the other people who are trying to control a single set of 3D map data are wrong, but for now it may be time to leave it alone. Investment is not the thing that will turn this best ever idea into something with a reasonable return. It's still lots of fun and we'll more than likely still bug you all with it until we find the killer app that makes it financially interesting.

Quakr presentation at XTech 2007

We, the Quakr gang will present our musings on Thursday 17th May at XTech 2007 in Paris, France.

Now... whether to have one of those presentations that consist of random colourful photos (creative commons, naturally), with just one word in white in the corner? Or is that just sooo 2005? Or, like flares, has it come around in a circle... ?

OK, I think what we'll do is put the viewr on autopilot on the screen behind us. I find walking through the floor and into the white void particularly vomitous.. perhaps we can set a record for mass induced motion-sickness...?

Building the World, one photo at a time
Is it possible to build a virtual world from user-contributed photographic metadata?

Short abstract:
This paper describes the experience of developing a 3D virtual world, based on publically available images and geo-metadata. A practical examination of the hardware, the standards, and real user practice.

Full abstract:

The Giants’ Approach: control everything
Google Earth and Microsoft’s Virtual Earth have 3D elements, but they have both chosen to control the data that creates those elements. Microsoft’s photo-realistic cities are ‘built’ from especially commissioned photos.

An Alternative: we the people
But the data is already out there. Amateur photographers have readily adopted the concept of location metadata; there are currently 0.5 million geotagged photographs on Flickr. Meanwhile, digital cameras embed Exif metadata (some already include GPS data), and geo-standards including KML and GML are in widespread use.

The view from 30,000 feet
Where are the overlaps between what the standards advocate, what cameras can provide, and what people actually do in practice?

Data (1): wish list
Is the data sufficient? What data does a 3D rendering engine ideally need to position photos in 3D space? Are the geo-standards sufficient to describe that data set? If not, how might they be extended? Could users realistically contribute that data set? What tools would help them?

Data (2): making do
Finally, to what extent can an open-world-minded application make sense of the sparse, ambiguous data which is avaliable right now?

Our application
This paper describes the experience of developing a 3D virtual world, based on publically available images and existing geo-metadata, including Flickr. We make recommendations for extending geo-metadata standards to facilitate such applications, and we document our D.I.Y. efforts at constructing a geo-camera of the future, capable of capturing the metadata we advocate.

Our application sits in the heart of the ubiqitous web, at the intersection between increasingly sophisticated gadgets, metadata standards, and the surprising extent to which users are prepared to indulge in both.
